Figure 5From: Pharmacoproteomic study of the effects of chondroitin and glucosamine sulfate on human articular chondrocytesMitochondrial superoxide dismutase (SOD2) is decreased by GS alone and in combination with CS. A. Underexpression values of SOD2 determined by real-time polymerase chain reaction (PCR) analysis on cultured human articular chondrocytes treated with interleukin-1β (IL-1β) plus GS and/or CS (n = 4, P < 0.05*). B. Western blot analysis of SOD2 protein levels in treated chondrocytes. A representative blot is shown, along with the numeric data obtained by densitometry analysis of the blots (n = 7, P < 0.05*).Back to article page
